DRM update randomly and temporarily locks up x250 with Firefox

Paul Irofti-4
>Synopsis: Default X configuration with Firefox temporarily locks up x250 with Firefox
>Category: kernel
>Environment:
        System      : OpenBSD 6.7
        Details     : OpenBSD 6.7-current (GENERIC.MP) #337: Wed Jul  8 10:37:10 MDT 2020
                         [hidden email]:/usr/src/sys/arch/amd64/compile/GENERIC.MP

        Architecture: OpenBSD.amd64
        Machine     : amd64
>Description:
        Ever since the DRM update the CPU will randomly go to (more than) 100%
        and lock-up the machine for 20-30 seconds to a few minutes. This is
        triggered faster when using Firefox (or other rendering programs).
>How-To-Repeat:
        Install -current on an x250 laptop and run Firefox on non-trivial
        websites. Example: web.whatsapp.com, drive.google.com, docs.google.com,
        dropbox.com, outlook.office365.com etc.
>Fix:
        $ cat /etc/X11/xorg.conf
        Section "Device"
          Identifier "default device"
          Driver "modesetting"
          Option "AccelMethod" "none"
        EndSection

FWIW, I have an x1 gen3 wich is essentially the same hardware.  I see
no such issues, but I mostly run chrome and I do have 8G of memory.

To me this sounds like you are running out of memory.  The DRM code is
supposed to give up any spare graphics buffers when asked to do so by
the pagedeamon.  But maybe that isn't working well for you.

Out of "video" memory or system memory? Are you saying low-memory
machines, which I don't think this laptop qualifies as but maybe things
expire more rapidly nowadays, are not supported by the new DRM code?
What are the minimum requirements? Can you try Firefox and see if you
can reproduce it? Maybe it is not memory.

Yeah, I just realized that this never happens to me on the Windows installation I have on this machine where I run basically the same software except for the OS. So it is not a hardware issue. I can try Ubuntu too if you want. And I am also available for debugging it on OpenBSD if you provide me with instructions on what to do.

Thank you,

.. or could be "not enough" so the pagedaemon is running and you are paging out,
.. or could be due to other things making you wait for memory.

My x250 works here, but I also have more memory.

having a look at what's waiting in ddb if you can drop to ddb while it is hanging is
often helpful.

Additionally you can often see things if you are running top -S -s 0.1 in a
window and watching it.
